This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,109.

Summary of the Inventive Concept

The present invention relates to an improved oil-less fryer stand device that addresses the limitations of the original patent by providing enhanced stability, efficient grease drainage, and optimized cooking time. The inventive concept comprises adjustable legs, a heat-resistant drip tray, and a weighted base, among other features.

Background and Problem Solved

The original oil-less fryer stand device patent has several limitations, including the lack of adjustability for accommodating varying sizes of cooking vessels, inefficient grease drainage, and potential instability during cooking. The present invention solves these problems by introducing novel features that improve the overall cooking experience.

Detailed Description of the Inventive Concept

The enhanced oil-less fryer stand device comprises a main body with adjustable legs that can accommodate varying sizes of cooking vessels. The legs are designed to maintain a stable cooking environment, ensuring that the vessel remains level and secure during cooking. A heat-resistant, detachable drip tray with a sloping surface is integrated into the device, allowing for efficient grease drainage and easy cleaning. Additionally, the device features a weighted base with a low center of gravity, providing enhanced stability and reducing the risk of tipping. The hollow pipe has a tapered end, ensuring secure vessel placement and preventing accidents. Furthermore, the device can be equipped with a pre-heating module and a temperature control unit, allowing for precise heat regulation and reduced cooking time. The inventive concept also encompasses a modular design, featuring interchangeable shelves of varying sizes and a universal mounting system for secure attachment.

Novelty and Inventive Step

The new claims introduce several novel features that distinguish the inventive concept from the original patent. The adjustable legs, heat-resistant drip tray, weighted base, and tapered hollow pipe are all new and non-obvious elements that provide significant improvements over the prior art. The inventive step lies in the combination of these features, which work together to create a more efficient, stable, and safe cooking environment.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the adjustable legs, such as telescoping or folding legs. The heat-resistant drip tray could be replaced with a different material or design, such as a ceramic or silicone tray. The weighted base could be modified to incorporate different materials or shapes, such as a circular or square base. Additionally, the inventive concept could be adapted for use with different types of cooking vessels or appliances.

Potential Commercial Applications and Market

The enhanced oil-less fryer stand device has significant commercial potential in the cooking industry, particularly in the health-conscious and environmentally friendly segments. The device's ability to provide a safe, efficient, and healthy cooking experience makes it an attractive option for consumers and commercial kitchens alike. Target industries include the food service industry, cookware manufacturers, and health-focused consumers.
